基于YOLOv9-B模型的港口船舶红外检测方法
lnfrared ship detection in harbor based on YOLOv9-B model
摘要
Abstract
To further enhance the safety and intelligence of port operations,intelligent detection methods for ships in the harbor under complex conditions are studied in this paper.It primarily addresses issues of detection inaccuracies caused by imaging blur due to environmental factors and the small size of vessel targets resulting from shooting angles.A high-precision infrared vessel detection model based on YOLOv9-B is proposed.Firstly,a multi-scale spatial attention module is designed,wherein traditional convolutions in spatial attention are replaced with multiple dilated convolutions to expand the receptive field and capture more local information.Secondly,a branch fusion attention mechanism is devised to enhance the focus on small and blurry targets by introducing efficient channel attention and multi-scale spatial attention,thereby reducing the loss of target information during feature fusion.Finally,the RepNCSPELAN4 module in YOLOv9 is replaced with the C2f module to strengthen feature extraction capabilities and improve detection accuracy.The ablation experiments are conducted on the infrared ship dataset and the self-constructed dataset in this paper,and the results show that compared with the YOLOv9 model,the proposed model improves the mAP by 1.6%and 1.9%,and improves the detection speed by 3.2 and 1.2 fps,respectively.At the same time,the comparative experiments show that the proposed model is superior to other mainstream models.关键词
